What makes rare untreated gems valuable for collectors?
Rare untreated gems for collectors, such as authentic untreated crystals and unheated and untreated stones, are prized for their natural appearance and limited availability. Their untouched state makes them highly desirable and a great investment.

I've made several purchases through GemSelect in the past, although not within the last six months. Their gems are always beautiful and I have never had an issue with their prices or their stones. Even when I'm not buying, I love scrolling through their website, which is very user friendly. I especially appreciate being able to change the listing order to your own liking, such as most to least expensive, largest to smallest, etc. As with most online orders, however, I think the shipping charges are not commensurate with the actual weight of the items shipped.
